CVE-2025-3519 Detail
Awaiting Analysis
This CVE record has been marked for NVD enrichment efforts. DescriptionAn authorization bypass in Unblu Spark allows a participant of a conversation to replace an existing, uploaded file. Every uploaded file in Unblu gets assigned with a randomly generated Universally Unique ID (UUID). In case a participant of this or another conversation gets access to such a file ID, it can be used to replace the file without changing the file name and details or the name of the user who uploaded the file. During the upload, file interception and allowed file type rules are still applied correctly. Metrics

vector strings. CVSS information contributed by other sources is also
